Wardrobing is a form of return fraud where an item is purchased, used, and then returned it to the store for a refund.
(Just going to quote the below article)
"The rising trend of ‘wardrobing’ is fast becoming one of the biggest challenges facing the retail industry, and it’s not just limited to apparel. A report from Brightpearl showed that 40% of retailers have seen wardrobing increase, and 44% agreed that their margins are being strongly impacted by handling and packaging returns. Furthermore, 70% revealed their business profits will be “further squeezed” as try-before-you-buy (TBYB) becomes more popular."
Not saying shes a bad person and millions of people do it worldwide .. but its just definitely not done without consequences for a business.
